Methods in io.debezium.connector.oracle.logminer that return Scn

Modifier and Type	Method and Description
Scn	Scn.add(Scn value) Returns a SCn whose value is (this + value).
private Scn	TransactionalBuffer.calculateSmallestScn()
static Scn	LogMinerHelper.getCurrentScn(OracleConnection connection) This method returns current SCN from the database
(package private) static Scn	LogMinerHelper.getEndScn(OracleConnection connection, Scn startScn, LogMinerMetrics metrics, int defaultBatchSize) This method returns next SCN for mining and also updates MBean metrics We use a configurable limit, because the larger mining range, the slower query from LogMiner content view.

Scn	LogFile.getFirstScn()
Scn	LogFile.getNextScn()

static Scn	Scn.valueOf(int value) Construct a Scn from an integer value.
static Scn	Scn.valueOf(long value) Construct a Scn from a long value.
static Scn	Scn.valueOf(String value) Construct a Scn from a string value.

Methods in io.debezium.connector.oracle.logminer with parameters of type Scn

Modifier and Type	Method and Description
Scn	Scn.add(Scn value) Returns a SCn whose value is (this + value).
static String	SqlUtils.archiveLogsQuery(Scn scn, Duration archiveLogRetention) Obtain the query to be used to fetch archive logs.
private void	TransactionalBuffer.commit(ChangeEventSource.ChangeEventSourceContext context, OracleOffsetContext offsetContext, Instant start, List<TransactionalBuffer.CommitCallback> commitCallbacks, Timestamp timestamp, Scn smallestScn, Scn scn, EventDispatcher<?> dispatcher)
(package private) boolean	TransactionalBuffer.commit(String transactionId, Scn scn, OracleOffsetContext offsetContext, Timestamp timestamp, ChangeEventSource.ChangeEventSourceContext context, String debugMessage, EventDispatcher dispatcher) Commits a transaction by looking up the transaction in the buffer and if exists, all registered callbacks will be executed in chronological order, emitting events for each followed by a transaction commit event.
